G4F-RD2A

Description

4-channel RTD input module for LS G4/GM4 PLCs, supports Pt100 / JPt100 input types.

The Polar Energy Assessment:

The G4F-RD2A is a special input module: 4 channels for resistive temperature detector (RTD) sensors. The module supports standard RTD types (e.g., Pt100) with 12-bit resolution, enabling temperature measurement in industrial automation systems.

Pros

• Direct RTD input support means fewer external signal conditioners needed.
• 4 channels gives moderate capacity for temperature sensing tasks.
• Good match for LS G4 PLC base systems.

Limitations

• RTD only; does not cover thermocouples (for which a different module is used).
• If more than 4 temperature points are needed, multiple modules must be used.

Typical use cases

• Monitoring temperature via Pt100 sensors in a control system using LS G4 PLCs.
• Panels where temperature feedback is required for process control or safety logic.
